Setting the Explicit Path for Dynamic Bypass LSPs

The user can configure an explicit path for the dynamic bypass LSPs for a protected interface. Use the primary-path command for this purpose.

To set the explicit path for dynamic LSPs, complete the following steps.

Enable the device for configuration.
```
device>configure
```
Enable the MPLS router.
```
device(config)# router mpls
```
Enable MPLS-capable interfaces and specify the selected Ethernet interface. In this example, the selected Ethernet interface is 0/8.
```
device(config-router-mpls)# mpls-interface ethernet 0/8
```

Enable the interface level dynamic bypass.

device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass

Configure the primary-path command. In this example, the primary path name selected is dbyp-path.
```
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# primary-path dbyp-path    
```

The following example combines the steps above to set an explicit path with the name of dbyp-path, for dynamic bypass LSPs.

device>configure
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/8
device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# primary-path dbyp-path
